relliker writes in with word of a paper up on the ArXiv by Seth Lloyd and co-workers, exploring the possibility that "postselection" effects in non-linear quantum mechanics might allow paradox-free time travel. "Lloyd's time machine gets around [the grandfather paradox] because of the probabilistic nature of quantum mechanics: anything that this time machine allows can also happen with finite probability anyway... Another interesting feature of this machine is that it does not require any of the distortions of spacetime that traditional time machines rely on. In these, the fabric of spacetime has to be ruthlessly twisted in a way that allows the time travel to occur. ... Postselection can only occur if quantum mechanics is nonlinear, something that seems possible in theory but has never been observed in practice. All the evidence so far is that quantum mechanics is linear. In fact some theorists propose that the seemingly impossible things that postselection allows is a kind of proof that quantum mechanics must be linear."

Gamasutra's Leigh Alexander recently wrote an editorial about the atmosphere of irritation and dissatisfaction that pervades all aspects of the video game industry. Developers are often overworked and unfulfilled, gamers have no qualms about voicing their disapproval (sometimes quite warranted, sometimes not), and the media, in trying to please both groups, often fails to satisfy either. Why is there so much strife in an industry ostensibly focused on having fun? From the article: "More and more developer sources I talked to suggested that fatigue, hostility, being at odds with one's employer and questioning one's career course is frighteningly common in the game industry. That being the case, it seems natural that elements like emotional detachment, anxiety and a lack of fulfillment make their way, even subtly, into the products the industry creates and into the ecosystem around the industry and its audience. 'Because of the secrecy and competition, a lot of development teams end up having a siege mentality — batten down the hatches and refuse to come up for air until the game's done,' says [an] anonymous developer. 'Game development has a way of taking over your life, because there's always more that can be done to improve perceived quality. I've seen a lot of divorces in my time in the game industry. I feel like it's much greater than average, but I have no statistical evidence.'"

sv_libertarian writes "They've faced down humans time and time again, but Fred Phelps and his minions from the Westboro Baptist Church were not ready for the cosplay action that awaited them at Comic-Con. After all, who can win against a counter-protest that includes robots, magical anime girls, Trekkies, Jedi, and... kittens?"

blackbearnh writes "Imagine that your data center was in the most geographically remote location in the world. Now imagine that you can only get to it 4 months of the year. Just for fun, add in some of the most extreme weather conditions in the world. That's the challenge that faces John Jacobsen, one of the people responsible for making sure that the data from the IceCube Neutrino Observatory makes it all the way from the South Pole to researchers across the world. In an interview recorded at OSCON, Jacobsen talks about the problems that he has to face (video), which includes (surprisingly) keeping the data center cool. If you're ever griped because you had to haul yourself across town in the middle of the night to fix a server crash, this interview should put things in perspective."

An anonymous reader writes "Sicily has just announced the opening of the world's first concentrated solar power (CSP) facility that uses molten salt as a heat collection medium. Since molten salt is able to reach very high temperatures (over 1000 degrees Fahrenheit) and can hold more heat than the synthetic oil used in other CSP plants, the plant is able to continue to produce electricity long after the sun has gone down. The Archimede plant has a capacity of 5 megawatts with a field of 30,000 square meters of mirrors and more than 3 miles of heat collecting piping for the molten salt. The cost for this initial plant was around 60 million Euros."

foregather writes "The Software Freedom Law Center has released some independent research on the safety of software close to our hearts: that inside of implantable medical devices like pacemakers and insulin pumps. It turns out that nobody is minding the store at the regulatory level and patients and doctors are blocked from examining the source code keeping them alive. From the article: 'The Food and Drug Administration (FDA) is responsible for evaluating the risks of new devices and monitoring the safety and efficacy of those currently on market. However, the agency is unlikely to scrutinize the software operating on devices during any phase of the regulatory process unless a model that has already been surgically implanted repeatedly malfunctions or is recalled. ... Despite the crucial importance of these devices and the absence of comprehensive federal oversight, medical device software is considered the exclusive property of its manufacturers, meaning neither patients nor their doctors are permitted to access their IMD's source code or test its security.'"

Trintech writes "According to MSNBC: 'The city of Oakland, California on Tuesday legalized large-scale marijuana cultivation for medical use and will issue up to four permits for "industrial" cultivation starting next year. The move by the San Francisco Bay Area city aims to bring medical marijuana cultivation into the open and allow the city to profit by taxing those who grow it. The resolution passed the city council easily after a nearly four-hour debate that pitted small-scale "garden" growers against advocates of a bigger, industrial system that would become a "Silicon Valley" of pot.' Yes, you read that right. MSNBC just compared computer chip fabrication to pot cultivation."

An anonymous reader writes "In a recent post by seven members of their security team, Google lashed out against the current standards of responsible disclosure, and implicitly backed the recent actions of Tavis Ormandy (who is listed as one of the authors). The company said it believed 60 days should be an 'upper bound' for fixing critical vulnerabilities, and asked to to be held to the same standard by external researchers. In another, nearly simultaneous post to the Chromium blog, Google also announced they are raising the security reward for Chrome vulnerabilities to $3133.7, apparently in response to Mozilla's recent action."

snydeq writes "InfoWorld's Peter S. Vogel reports on the kinds of inadvertent transgressions that could land IT pros into legal trouble without realizing it. From confidentiality and privacy negligence, to copyright and source code violations, IT staff are legally liable for a lot more than they might think — in some cases because the law will not stop at your employer, instead holding individual IT employees responsible for violations even if the individuals are just 'doing their job.' Worse, as the recent case against Terry Childs has shown, judges and juries are often not technically savvy enough to understand what IT pros do. 'That lack of understanding can lead them to conclude you're at fault or should have known better,' Vogel writes. 'After all, many people think anyone technical is a whiz kid or brainiac on any topic.'" What legally questionable scenarios have cropped up at your job?

J. Dzhugashvili writes "If you read Slashdot, odds are you already know about WiGig and the 7Gbps wireless networking it promises. The people at Atheros and Wilocity are now working on an interesting application for the spec: wireless PCI Express. In a nutshell, wPCIe enables a PCI Express switch with local and remote components linked by a 60GHz connection. The first applications, which will start sampling next year, will let you connect your laptop to a base station with all kinds of storage controllers, networking controllers, and yes, an external graphics processor. wPCIe works transparently to the operating system, which only sees additional devices connected over PCI Express. And as icing on the cake, wPCie controllers will let you connect to standard Wi-Fi networks, too."

Sir Mal Fet writes "Chile has become the first country in the world to approve, by 100 votes in favor and one abstention, a law guaranteeing net neutrality (Google translation; Spanish original). The law states [submitter's translation]: 'No [ISP] can block, interfere with, discriminate, hinder, nor restrict the right of any Internet user of using, send, receive or offer any content, application, or legitimate service through the Internet, as well as any activity or legitimate use conducted through the Internet.' The law also has articles that force ISPs to provide parental control tools, clarify contracts, guarantee users' privacy and safety when surfing, and forbids them to restrict any liberty whatsoever. This is a major advance in the legislation of the country regarding the Web, when until last year almost anything that was performed online was considered illegal."

kkleiner writes "A telescopic implant that fits directly into the eye to treat certain kinds of blindness has finally received FDA approval for use in the US after more than five years of waiting. The Implantable Miniature Telescope (IMT) is used to treat age-related macular degeneration (AMD), a condition that affects millions around the world. For many, the center part of their vision becomes blurred or completely dark. The IMT is surgically implanted into the cornea and acts to expand an incoming image onto the peripheral parts of the retina that are undamaged by AMD. The commercial version of the IMT is called CentraSight and is in development by VisionCare Inc. There are likely hundreds of thousands of potential patients in the US alone who may be able to have their vision partially restored now that CentraSight has garnered FDA approval."

Hugh Pickens writes "The NY Times reports that although allergies and the promise of air-conditioning tend to drive people indoors at this time of year, when people spend time in more natural surroundings — forests, parks, and other places with plenty of trees — they experience increased immune function. A study of 280 healthy people in Japan, where visiting nature parks for therapeutic effect has become a popular practice called 'Shinrin-yoku,' or 'forest bathing,' found that being among plants produced 'lower concentrations of cortisol, lower pulse rate, and lower blood pressure,' among other things. Another study in 2007 showed that men who took two-hour walks in a forest over two days had a 50-percent spike in levels of natural killer cells, and a third study found an increase in white blood cells that lasted for a week in women exposed to phytoncides in forest air."

Knowzy writes "At least two divisions at HSBC Bank apparently failed card issuing 101 and are mailing out debit cards pre-activated. Because they are debit cards, fraudulent transactions come directly out of a victim's checking account. A similar report from 2004 suggests this issue is longstanding and widespread. When confronted with the evidence, HSBC would not commit to fixing this issue, preferring instead to offer vague statements like, 'Through our systems and analytics, we focus on the greatest and most active threats in an effort to avoid negatively impacting customer experience.'"
